'VACUUM SWEEPER to provide a vacuum sweeper having few.

parts and which are easily accessible and can be quickly changed.

Other objects will also be evident from the following descrlption taken in connection with the drawings, which form a part of this specification, and in which:

Fig. 1 is broken sectional view of a vacuum 2o cleaner showing the application of this invention.

Fig. 2 is a view taken on line 2-2 of Fig. 1 brokenaway, to show a plan view of the construction.

Fig. 3 is an enlarged perspective view of the brush operating device.

Fig. 4 is an inverted sectional view of the nozzle or suction head of the sweeper.

Fig. 5 is a perspective view of the pres- 30 sure spring shown in Fig. 4.

Fig. 6 is a perspective view of inner bracket which holds the brush in position.

Referring to the drawings, Figs. 1 and 2 illustrate a vacuum sweeper havingv a motor- 1, fastened to body 2 by bolts 3 and which has a dust bag 4 appended at the rear thereto and a foot 5 to which a roller 6 is attached for propelling the cleaner.

The forward brush housing 6 of vacuum chamber 7 has an inner bent or U-shaped bracket bar or holder 8 the main bar of which is offset at the middle and slotted at 9 to slidably engage pin 10 fixed in brush `rod 11 the rod being held in position by means of openings 12 in the end walls 13 of the bracket A ,slot 9 thus producing a sweeping movement of 8 which fits closely at its ends in the housing 6 and is held in position by the pressure of a spring 31 causing notches 32 in the ends of the arms 13 to engage pins 33 projecting through the side walls of the housing 6.

The fan 14 having a plurality of curved fins 15, in revolving cause a suction of air through the brush housing 6 drawing dirt and other like substance through vacuum chamber 7 into dust bag 1 4 as it is swept up by the action of the plurality of brushes 16 that are fixed in or secured to brush rod 11.

The eccentri'c17 has a smaller end 18 which is circled by the open end 19 of the end connection 20 of a connecting rod and is held in position by a cap 21.

The eccentric portions 17 and 18 and ca 21 have an opening 22 off center thru which olt 23is inserted and` fastened to the fan 14.

The end connection 2O of the connecting rod is connected to the exible middle or spring portion 24 by means of a clip 25 and bolt, or rivet 26, the spring portion in turn bein fastened to the opposite end connection 27 having at the extreme end an opening 30 thru which pin 10 extends, the end of the bar 27 working in the oii'set part of the bar 8.

As the' fan 14 revolves the eccentric and connecting rod cause the pin 10 to slide in the the brushes 16; the ends of pressure spring 31 pushing against housing 6 causes the center of spring\\to press against inner bracket 8 thus preventing vibration of the brush ,rod 11, and this spring also prevents displacement of the brush pin 10.

I claim:

1. The combination with the suction nozzle of a lvacuum sweeper the sidewalls of the nozzle having inner projections, of an oscillating brush extending. across the nozzle, a U-shaped bracket bar fitting in the nozzle and supporting the brush, the ends of said bar fitting against said side walls and having 9' notches in which said projections are engaged, and means to osoillate the brush.

2. The combination with the suction nozzle of a vacuum sweeper, of an oscillating brush extending across the nozzle, an inverted U- shaped bracket bar fitting in the nozzle and supporting the brush, the bracket bar having a slotted oiset part at the middle, a pin projecting from the brush and through said slot, and means to oscillate the brush including a rod Working in the o'set of the bar and engaging sald pin.

In testimony whereof, I do ahx my signature.
